When fib_default_rule_add is invoked, the value of the input parameter
'flags' is always 0. Rules uses kzalloc to allocate memory, so 'flags' has
been initialized to 0. Therefore, remove the input parameter 'flags' in
fib_default_rule_add.

The top_dp and top_edp muxes can be both parented to either TVDPLL1
or TVDPLL2, two identically specced PLLs for the specific purpose of
giving out pixel clock: this becomes a problem when the MediaTek
DisplayPort Interface (DPI) driver tries to set the pixel clock rate.
In the usecase of two simultaneous outputs (using two controllers),
it was seen that one of the displays would sometimes display garbled
output (if any at all) and this was because:
- top_edp was set to TVDPLL1, outputting X GHz
- top_dp was set to TVDPLL2, outputting Y GHz
- mtk_dpi calls clk_set_rate(top_edp, Z GHz)
- top_dp is switched to TVDPLL1
- TVDPLL1 changes its rate, top_edp outputs the wrong rate.
- eDP display is garbled
To solve this issue, remove all TVDPLL1 parents from `top_dp` and
all TVDPLL2 parents from `top_edp`, plus, necessarily switch both
clocks to use the new MUX_GATE_CLR_SET_UPD_INDEXED() macro to be
able to use the right bit index for the new parents list.

Add support for customized parent indices for MediaTek muxes: this is
necessary for the case in which we want to exclude some clocks from
a mux's parent clocks list, where the exclusions are not from the
very bottom of the list but either in the middle or the beginning.
Example:
- MUX1 (all parents)
- parent1; idx=0
- parent2; idx=1
- parent3; idx=2
- MUX1 (wanted parents)
- parent1; idx=0
- parent3; idx=2
To achieve that add a `parent_index` array pointer to struct mtk_mux,
then in .set_parent(), .get_parent() callbacks check if this array
was populated and eventually get the index from that.
Also, to avoid updating all clock drivers for all SoCs, rename the
"main" macro to __GATE_CLR_SET_UPD_FLAGS (so, `__` was added) and
add the new member to it; furthermore, GATE_CLK_SET_UPD_FLAGS has
been reintroduced as being fully compatible with the older version.
The new parent_index can be specified with the new `_INDEXED`
variants of the MUX_GATE_CLR_SET_UPD_xxxx macros.

CXL CPER events are identified by the CPER Section Type GUID. The GUID
correlates with the CXL UUID for the event record. It turns out that a
CXL CPER record is a strict subset of the CXL event record, only the
UUID header field is chopped.
In order to unify handling between native and CPER flavors of CXL
events, prepare the code for the UUID to be passed in rather than
inferred from the record itself.
Later patches update the passed in record to only refer to the common
data between the formats.
Pass the UUID explicitly to each trace event to be able to remove the
UUID from the event structures.
Originally it was desirable to remove the UUID from the well known event
because the UUID value was redundant. However, the trace API was
already in place.[1]

Merge tag 'apparmor-pr-2024-01-03' of git://git.kernel.org/pub/scm/linux/kernel/git/jj/linux-apparmor
Pull apparmor fix from John Johansen:
"Detect that the source mount is not in the namespace and if it isn't
don't use it as a source path match.
This prevent apparmor from applying the attach_disconnected flag to
move_mount() source which prevents detached mounts from appearing as /
when applying mount mediation, which is not only incorrect but could
result in bad policy being generated"

Since util-linux commit 13b26e3c36d1
("fdformat: remove command from default build")
the fdformat tool is not built anymore by default.
As a result it is not packaged anymore by distributions and therefore
not usable by users.
Instead mention the "mount" command as more likely to be present
alternative.
Also drop the reference to fdformat from the list of features of new
versions of util-linux.

We know the macro DEBUG will make pr_debug() save the formatted

When there are filenames of the form ".orig" or ".rej" in
the Documenatation/ABI/ subdirectories, there can be confusing or
erroneous output generated. Example: the file
Documenation/ABI/testing/sysfs-bus-papr-pmem.orig causes this
warning message:
Documentation/ABI/testing/sysfs-bus-papr-pmem:2: WARNING: unknown document: '/powerpc/papr_hcalls'
Prevent this by skipping over filenames that may be created by
patch/diff tools etc.

/sys/devices/cpu_core/events/cpu-cycles. The cycles event is a legacy
event but with no sysfs version.
Add a test that the sysfs version is preferred to the legacy for
cpu-cycles, while for cycles we use the legacy version.
